Tom Hiddleston, Elizabeth Olsen Dating: 'Avengers' Romance Rumors [WATCH]

Watch out, Thor, Scarlett Witch and Loki are dating! The younger sister of Mary-Kate and Ashley Olsen, Elizabeth Olsen 26, was seen sharing a cab with Tom Hiddleston 34, in London after seeing Bradley Cooper perform in The Elephant Man. Hiddleston plays Thor's evil brother Loki in Marvel's Thor films and, recently, Olsen starred in Avengers: Age of Ultron as Wanda Maximoff (aka Scarlett Witch).

Although they both play characters in the Marvel Avengers universe movies, they haven't yet appeared in a Marvel film together.  Currently, there are no notes of the two of them sharing the screen in the next few Marvel movies.  Hiddleston will be Loki in the next Thor film, Thor: Ragnarok, scheduled to be released in 2017 and hasn't even begun filming, while Olsen will return as the Scarlett Witch in Captain America: Civil War, which is filming right now and will be released in May of 2016. "The couple [also] recently wrapped filming the drama I Saw the Light, based on country legend Hank Williams' life in which they play Williams and his wife, Audrey Mae Williams, respectively," reports Us Weekly. For reasons just like this, Olsen has always stated that that is why she isn't on any type of social media and prefers to keep her personal life private. Her discomfort with the paparazzi is evident from the video on YouTube, posted from DailyMail Online.

According to Huffington Post, the couple was first rumored to have had some sort of romantic relationship "Back in May, [when] Us Weekly first reported the two [were] romantically involved, although neither has confirmed the relationship. They were also the first to report Olsen broke off her engagement to Boyd Holbrook in January."

Do you think the two are really dating or is this an unnecessary buzz about two close co-workers and friends? I Saw the Light comes to theaters in November starring the cute new pair. Perhaps the on-screen chemistry in this film will further fuel dating rumors?
